Return on Investment is a performance measure used to evaluate the efficiency of an investment or compare the efficiency of a number of different investments. ROI will directly measure the amount of return on a particular investment, relative to the investment's cost. To calculate ROI, the return of an investment is divided by the cost of the investment. The result is expressed inpercentage or a ratio. ROI is a famous metric because of its versatility. Essentially, ROI can be used as a tool to find an investment's profitability. This could be the ROI on a stock investment, the ROI a company expects on expanding a factory, or the ROI generated in a real estate transaction. The calculation is relatively easy to interpret for its wide range of applications. If an investment's ROI is net positive, it is probably worthwhile. The investors should avoid negative ROIs, which imply a net loss. Calculation ROI ROI = Current value of investment - Cost of investment / Cost of investment Example Suppose Sachininvested $1,000 in MRF Corp. in 2017 and sold his stock shares for a total of $1,200 one year later. To calculate his return on his investment, sachin would divide his profits ($2,200 - $2,000 = $200) by the investment cost ($2,000), for a ROI of $200/$2,000, or 10 percent. With this information, he could compare his investment in Slice MRF with his other projects. Suppose Sachin also invested $2,000 in DSI Inc. in 2014 and sold his shares for a total of $2,800 in 2017. The ROI on Sachin's holdings in DSI would be $800/$2,000, or 40 percent. Importance of ROI ROI is a profitability ratios.

Earnings per share (EPS) Earnings per share (EPS) is a company's net profit divided by the number of common shares it has outstanding.EPS indicates how much money a company makes for each share of its stock. It is a widely used metric for corporate profits.A higher EPS indicates more value because investors will pay more for a company with higher profits.EPS can be arrived at in several forms, such as excluding extraordinary items or discontinued operations, or on a diluted basis. The earnings per share metric isone of the most important variables in determining a share's price. It is also a major component used to calculate the price-to-earnings (P/E) valuation ratio. By dividing a company's share price by its earnings per share, an investor can see the value of a stock in terms of how much the market is willing to pay for each dollar of earnings.EPS is one of the many indicators you could use to pick a stocks. Comparing EPS in absolute terms may not have much meaning to investors because ordinary shareholders do not have direct access to the earnings. Instead, investors will compare EPS with the share price of the stock to determine the value of earnings and how investors feel about future growth. Formula of EPS The earnings per share value are calculated as the net income (also known as profits or earnings) divided by the available shares. The numerator of the equation is also more relevant if it is adjusted for continuing operations.To calculate a company's EPS, the balance sheet and income statement are used to find the period-end number of common shares, dividends paid on preferred stock (if any), and the net income or earnings. It is more accurate or better to use a weighted average number of common shares over the reporting term because the number of shares can change over period of time. EPS = Net income - Preffered divident / End of period common shares outstanding or Weighted average shares outstanding Example XYZ Ltd has a net income of $2 million in the third quarter. The company announces dividends of $350,000. Total shares outstanding is at 15,000,000. The EPS of ABC Ltd. would be: EPS = ($2,000,000 - $350,000) / 15,000,000 EPS = $0.11 Types of EPS Basic EPS Diluted EPS Importance of EPS It measures profitability of the company It is an determinant of P/E ratio It is an indiactor of divident payout It helps investors to make informed decisions It allows investors to compare investments across sectors, industries and to an extent also with alternative investments. It also helps to chart the financial performance of a particular company over time. ROE vs. EPS The ROE is a better indicator than simple EPS of how a company is deploying its capital to build a profitable business. A company's ROE should be compared to that of its competitors and other companies in the same sector, whereas EPS and P/E ratios are better used as a gauge of whether the shares themselves are over or undervalued. The higher the ROE, the more wealth the company is creating for its shareholders, and the better return they can expect from their investment. so all the are the details of ROI and EPS
